How to register an antique watch on Patek website?

[qrc36]

I just got an antique Patek pocket watch from an auction. I have an Extract from the Archives.

Is there a way to register this on the Patek website?

I've done it for new watches with the "Owner Registration" function on the website. However, there is no "Watch Reference Number" on the Archives for this watch. There is only a case number and movement number.

And since the retailer is an auction house, I don't know how to fill in retailer's country/city/name.

Any ideas? Or is there no way to register my ownership of this piece?

Thanks!

Thanks to the person who sent me a private message. Wanted to share the answer in case someone has a similar question in the future.

A simple email to owners@patek.com together with the Extract of the Archives will start the registration process. They will ask a few more questions but it was relatively straightforward.
